Calibration of Radiation Sources for Radiography

A survey was conducted to find and evaluate published national standards for calibration of radiation sources used in industrial radiography. No standards were found on this specific subject, although several standards for medical radiography were discovered and summarized. The latter are inadequate for industrial radiography, but serve as general guidance on the subject. The need for an industrial standard was discussed, and a specific mechanism for developing such a standard was suggested if the need is considered to be sufficient.
